Yes, it's that simple. A bit of crimson has the power to put men in a lusty state of mind—one study even found they were 56 percent more likely to ask out a woman in a red top versus a white one. That's because men are hardwired to respond to the hue: The color was used as early as 10,000 B.C. in lip color and blush to mimic the red flush we get when we're turned on. Throw on a red dress and let primal instincts take over.

It's no surprise that anyone would be drawn to a megawatt grin, but what is fascinating is that a smile amps up how sexy you seem, according to a recent study. "A friendly and approachable woman may seem more sexually interested," researchers at the University of British Columbia told Allure. We can't vouch for the science on this part, but a little whitening could be nice, too. We like Crest 3D White 2 Hour Express Whitestrips, which brighten teeth in two hours.

Practically nothing about Victoria's Secret models is attainable—except possibly their shiny, soft hair. To achieve Angel-worthy gloss, try these shine-boosting techniques: Condition first, shampoo second. "For hair to be full and bouncy, it has to be free of residue," says hairstylist Nathaniel Hawkins. Then rough-dry hair by raking your fingers through it; if you want sexy volume, you have to embrace a little fluff. And when you think your hair's dry, blast it with heat for another three minutes. "It has to be 100 percent dry, otherwise it will collapse," says Hawkins. Mist a shine spray like Umberto Beverly Hills Shimmer Shine Spray over the whole head and voilá—you're halfway to Gisele.

We asked perfumers for the sexiest notes, and they all came back with the same answer: lush flowers, vanilla and amber, and powdery notes. One of our favorite seductive scents is Chanel No. 19 Poudre: French for "powder," this scent's fresh iris root tempers the heady jasmine. Dolce & Gabbana Velvet Sublime, with zesty orange blossom and intoxicating neroli, is warm, like a beach vacation in a bottle. Tom Ford Jasmin Rouge isn't for the faint of heart, or head. Ford tossed in the whole spice cabinet—cardamom, cinnamon, and ginger are sweetened by vanilla and warm amber.

It goes without saying that candlelight is sexy (there's a reason most Instagram filters wash everyone in a hazy glow), and the best way to flatter exposed skin is with a shimmery body cream. Dust Urban Decay's Honey Body Powder over your shoulders and décolletage, where light will naturally enhance it. We love it because it's a superfine, subtle, somehow grown-up shimmer, and—wait for it—it's lickable. Just saying.

Blinking, nodding, shaking your head: Weird but true that doing a lot of all three can make you more attractive to the average guy. A study found that women with "high-motion faces" (yes, that's actually what they were called) rated as best looking. Researchers at the University of Bristol told Allure it's likely because these moves signal that you're extroverted—and that's sexy.
